Quinoxaline 1-oxide metal complexes

Note Only a few simple examples of the metal complexes formed by quinoxaline oxides and dioxides are given here. 

Quinoxaline 1-oxide gave complexes with the chlorides of Cr, Mn, Fe, Co, Ni, Cu, and Zn also with the perchlorates of the same metals. Quinoxaline 1,4-dioxide gave complexes with the chlorides of Cr, Mn, Fe, Co,...

The ultraviolet spectrum of quinoxaline 1-oxide in a Nujol mull shows 238, 252 sh, 325, 340 sh, and 348 nm. Both ultraviolet and infrared data have been used to assign structures to the complexes quinoxaline 1-oxide forms with transition metal chlorides.
